战车火控系统射击命中三要素函数误差分析

火控系统射击(函数)误差可分解为射弹散布函数误差和火控射击准备函数误差。而射击准备函数则是命中三要素函数即瞄准函数、解算函数和控制函数的合成函数。命中三要素的提出,为火控系统射击误差(精度)的分析提供了新的途径。它们均是命中目标的关键要素,又各具特色,为火控系统射击精度乃至系统反应速度的提高,指出了应该努力的方向。针对此进行了具体的分析。     

The causal nexus between military spending and unemployment in the G7: a bootstrap panel causality test

We revisit the causal relationship between military spending and unemployment in the G7 countries applying a bootstrap panel causality analysis that accounts for both cross-sectional dependence and for heterogeneity across countries. Using per capita real GDP as a controlled variable, we found a unidirectional causality running from military spending to unemployment for Canada, Japan, and the US, one-way causality running from unemployment to military spending for France and Germany, and bidirectional causality for Italy and the UK. The empirical evidence does not seem to provide consistent results regarding the causal relationship between military spending and unemployment in G7 countries.     

基于事件分解的电磁脉冲前门耦合效能评估方法

电磁脉冲弹是一种利用辐射高功率电磁脉冲干扰/毁伤目标电子系统的新概念武器。为计算电磁脉冲通过前门耦合毁伤目标的效能,提出一种基于事件分解的效能评估方法,按时间序列将前门耦合-毁伤过程分为弹体爆炸辐射功率、电磁能量传输衰减、目标系统耦合3个子事件,分别用不同算法计算不同子事件的发生效能。用这种方法对美国MK.84导弹搭载的电磁脉冲弹进行评估,得到一定参考价值的效能评估值。     

Dynamic regulation on innovation and adoption of green technology with information asymmetry

This study investigates a regulator's dynamic policy to motivate firms' research on and adoption of green technology. In the proposed model, a firm makes unobservable efforts and can hide the technology's arrival from the regulator to avoid adoption costs. We find that the optimal policy follows a simple structure and induces part-time efforts, rather than the maximal effort reported in previous studies. In particular, the regulator should offer no subsidy before the arrival of a technology report, provide a one-time subsidy contingent upon that report, and always set a termination deadline. At the deadline, the firm is forced to select an external option that is associated with social costs. The optimal report-based subsidy decreases with time. Under the optimal policy, the firm works until an effort deadline, makes no effort thereafter, and reports the technology as soon as it arrives. This study also characterizes the necessary and sufficient conditions under which the optimal policy reduces to one that leads, in terms of throughout time, to effort that is maximal or minimal. Our results indicate that policymakers should implement a policy that compensates firms more in the present and less in the future.
